Actinium extracted from uranium ores is the isotope actinium-227 which has half-life of 21.7 years. It occurs naturally as one of the sequence of isotopes that originate with the radioactive decay of uranium-235. A tonne of pitchblende contains around 150 mg of actinium. Glossary Actinium is a radioactive element with an atomic number 89 of the periodic table. It has the physical appearance of metallic silver. In nature, it is found in traces of most of the Uranium ores. Due to intense radioactivity, this metal glows blue in the dark. It also shares similar properties to that of lanthanum Actinium is a chemical element with the symbol Ac and atomic number 89. It was first isolated by Friedrich Oskar Giesel in 1902, who gave it the name emanium; the element got its name by being wrongly identified with a substance André-Louis Debierne found and called actinium. Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the. Sulfura de actiniu se prepară în urma reacției dintre oxidul de actiniu cu acidul sulfhidric și sulfura de carbon, la temperatura de 1100 °C. Oxalatul de actiniu, Ac 2 (OX) 3 *H 2 O, este preparat din soluție de Ac 3+ în H-COOH la 90 °C, introducând dimetiloxalat care va produce ionul oxalat necesar prin procesul de hidroliză
